I'm doing all this to try to work around bug
<http://bugzilla.mozilla.org/show_bug.cgi?id=75607> "Can't create
factories for several components in embedding case".  Please see the bug
for background.

It turns out that Factory creation somehow gets messed up when I link my
app with -lwidget_gtk on Unix.  My workaround is to remove -lwidget_gtk
from my link line and get the necessary symbol at runtime using
PR_LoadLibrary/PR_FindSymbol.  This works on Solaris, but not on linux.
For soe reason, the symbol I'm looking for, "handle_gdk_event", isn't
found on Linux, even though it shows properly in nm, and PR_LoadLibrary
returns ok.

[edburns@dsl199-33 components]$ nm libwidget_gtk.so | grep handle_gdk_event
00048b54 T handle_gdk_event__FP9_GdkEventPv
[edburns@dsl199-33 components]$ c++filt
handle_gdk_event__FP9_GdkEventPv
handle_gdk_event(_GdkEvent *, void *)

Can someone please help me with this?

Ed
